Battle has raged between the Walt Disney Company (NYSE: DIS) and Netflix, Inc. (NASDAQ: NFLX) for more than two years, ending in a leery cease-fire last December when the two finally inked a deal to bring Disney content to the streaming service.

But, as Netflix has a production business -- and won an Emmy Award for its original “House of Cards” series on Sunday night -- some bitterness on Disney's part toward the newcomer seems to be rearing its head again.

Disney CEO Robert Iger cast doubts on the online service’s future on Tuesday, telling an audience at Goldman Sachs’ (NYSE:GS) Communacopia conference that it will be “really hard for them to corner the marketplace.”

“This is far from over,” he said, according to The Street.

He’s right -- the market is getting crowded.

Amazon.com's (NASDAQ:AMZN) Prime service and Hulu, the television-streaming service brainchild of a group of networks, are formidable competitors. And Apple Inc. (NASDAQ:AAPL) and Google (NASDAQ:GOOG), which until now have only dipped their toes into the TV streaming business, may soon enter in a serious way.

A Netflix spokesperson did not immediately respond to requests from International Business Times for comment.
